T ctZZ whom it may concern.-

Be it known that I, FRANK C. RINscHE, a vcitizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and useful Improvement in Engines, of which the following is a full, clear, and exact description, referenceA being had to the accompanying drawings, forming a part of this specitication, wherein- Figure l isa longitudinal sectional View. Fig. 2 is a similar view showing the piston in a different position; Fig. 3, a side elevational view of the piston. Fig. 4 is a cross-sectional view o n line 4 4, Fig. 2.

This invention relates to a new and useful improvement in engines of that class which are adapted to be run by compressed air or steam. In the end of the cylinder a tool-shank is inserted, which is operated upon by a stein zo or piston delivering impacting blows.

The invention contemplates the use of a three-headed piston in which are formed suitable ports, the inlet-port being let into the side of the cylinder, while the exhaust-port leads from the cylinder at different points, said exhaust-port beingcontrolled by a valve or some other suitable means, by which the speed of the engine is regulated.

In the drawings, A indicates the cylinder,

3o which is formed with the tool-shank opening A in its end, an inlet-port A" in its side, and an exhaust-port B, which opens into the side of the cylinder at points b b', said exhaustport leading to one end of the cylinder into an annulus b, which is formed in the end of the cylinder.

The cylinder-head C is seated on a shoulder in the open end of the cylinder, which cylinder-head is held in position bya handle-base,

4o which is screwed or otherwise secured to the cylinder.

Arranged transversely the handle-base is a plunger or valve E, which is forced by a spring E to normally 'close an opening e in the han- 4 5 dle-base, which leads from the exhaust-annulus b". A trigger in the form of a bell-crank lever is pivoted on the handle-shank, one end of which is received in an opening in the end of the plungershank. By depressing the 5o free end of the bell-crank lever or trigger, as shown in Fig. l, the plunger E is raised, so as to unclose the opening e and permit the ex-V haust to escape. `When the trigger is released, as shown in Fig. 2, the spring E forces the plunger downward and shuts ott the escape of the exhaust. This will cause the engine to cease running. By partially unclosing opening e the engine will run at a slow speed, its full speed beine, attained when the plunger is raised to permit the exhaust to es- 6o cape Without interruption. l

F indicates the piston, which is provided with a stemf, extending down into the toolshank opening A. This piston F is formed with heads F', F2, and F3, and also provided 65 with ports f andf, leading from the end of the piston and opening through the sides thereof beyond the central head F2.

The operation is as follows: Motive fluid being supplied through inlet-port A, assum- 7o ing the piston to he in the position as shown in Fig. l, will enter the cylinder and pass through portf to the upper end of the cylinder, forcing the piston down. The air in the lower end of the cylinder will `exhaust through port f and exhaust-opening b into the exhaust-port B, annulus b, through opening e `to the exterior. The downward movement ot' the piston causes head F2 to cross the inletport lopening A", which directs the motive 8o Huid through the opening f. Before the head F2 admits motive fluid to the lower end of the cylinder head F closes exhaust-port b to preventthe motive iiuid blowing through. Head F3 in the same movement uncloses ex- 85 haust-port b', permitting the air at the upper end ot' the cylinder to exhaust through port f into exhaust-port D, annulus 1),and openp ing e.4 The incoming motive duidv passes through port fand beneath head F3,forcing 9o the'piston upwardly. This cycle of operations is repeated, the piston controlling the inlet and exhaust.

I-Iaving thus described my invention, what I claim, and desire to secure by Letters Patent, is

l. In an engine, the combination with a cylinder formed with an annular recess in its ends, into which leads the exhaust, ot' a handle base which is adapted to be secured to roo said cylinder and close the annular recess, an opening in the handle base which opens into a handle base which is secured to the cylin-v der and holds the cylinder head in position, the exhaust of the engine passing up the side of the cylinder and through the handle base,

.and means on the handle base for controlling the exhaust; substantially as described.

3. In an engine, thecombination with the cylinder having an inlet port leading to its side, exhaust ports leading from the sides of the cylinder on each side of the inlet port, and a piston provided with three heads for controlling said ports, said piston being formed With passages which lead from the ends thereof to beyond the middle head, which middle head controls the inlet port, whereby, when the fluid is exhausting rfrom one end of the piston-chamber, it returns through the piston passage to the exhaust port farthest from the end exhausting, the head at the exhausting end, closing the nearest exhaust port; substantially as described.

4. In an engine, the combination with the cylinder having an'inlet port leading to its side, exhaust ports leading from the sides of the cylinder on each side of the inlet port, a piston provided with three heads for controlling said ports, said piston being formed With passages which lead from the ends thereof to beyond the middle head, which middle head controls the inlet port, whereby, when the iuid is exhausting from one end of the piston-chamber, it returns through the piston passage to the exhaust port farthest from the end exhausting the head at the exhausting end, closing the nearest exhaust port, a port B connecting said exhausts, and means located at the end of the cylinder` for controlling the escape of the exhaust through port B; substantially as described.

5. In an engine, the combination Wit-,h the cylinder having an inlet port leading thereinto about midway its length, and an exhaust port B which is arranged at the side of the cylinder into which it opens at points b and b', and leads to the end of the cylinder, of a piston provided with three heads cooperat ing with said inlet and exhaust ports, and means located at the end of lthe cylinder for controlling the escape of the exhaust through port B; substantially as described.

In testimony whereof I hereunto aiiix my signature, in presence of two Witnesses, this 18th day of February, 1895.
